To all whom it may concern:

Be it known that I, JOHN W. PAUL, a. citizen of the United States, residing at Kittanning, in the county of Armstrong and State of Pennsylvania, have invented new and useful Improvements in Type-W'riting Machines, of which the following is a specification.

This invention relates to typewriting machines and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

More particularly the inven'ion relates to the carriage scapement.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 shows a section on the line 11 in Fig. 2. Fig. 2, a section on the line 22 in Fig. 1.

1 marks the frame as a whole; 2 the side of the frame; 3 a cross piece'at the rear'of the frame 4 a horizontal. plate extending forwardly from the cross piece 3 5 a downwardly extending lip at the front of the plate 4.

6 marks the carriage. The rails 7 extend across the machine at the back edgeof the carriage. These rails are provided with the grooves 8. The carriage rail 9 is secured to the rear part of the carriage and is provided with the groove 10. The Wheels 11 are arranged in the grooves 8 and 10, forming a roller bearing for the carriage. The carriage rack 12 is at the bottom of the carriage and meshes a gear 13. The gear 13 is pivoted on the shaft 14. The shaft 14 is supported by a post 15 extending upwardly fromthe plate 4. The gear 16 is journaled on the shaft Hand is fixed With the gear 15 by any desired means. (Not shown.) A pinion 17 meshes the gear 16. The pinion is fixed on the shaft 18. The shaft is journaled in the post 15. An escapement wheel 19 is fixed on the front end of the shaft 18.

A hanger 20 is secured to the lip 5 and extends forwardly and forms a bearing for a reciprocating rod 21. The front end of the reciprocating rod is screw threaded and the head 22 is secured on this rod. A jam nut 23 secures the head in place. The head has the slot 23. A link 25 extends into this slot and is pivo'tally connected with the head 22. The link is pivotally connected at 26 with the universal bar 27. Thevuniversal bar is car-' ried by the levers 28, one'at each side of the machine. These levers are pivoted near the rear of the machine in any desired manner.-

slot extends over a rod 36. The rod 36 is fixed in swinging rock arms 37, one at each side of the machine. The fixed relation'of the rodwith the rock arms compelling a parallel movement of the rock arms. An extension 38 has a slot 39 which engages the rod 36. This extension is fixed on the bearing 40 and the ends of the hearing are prefera'bl connected with the rock arms 41. The roc arms 41 are fixed on the .rod 42. A rock arm 43 extends downwardly from the rod 42' and is connected by a link '44 with a lever The lever swings from a hanger 46 below the plate 4 and extends into a slot 47 in the rear of the sleeve-32 and it is pivotally connected with said sleeve 32. into a spring socket 48 which acting on the lever, tends to hold the sleeve 32 in a forward position so that the dog 31 is in the path of the escapement wheel.

In the operation of the ty versal bar is operated in t e usualmanner and its movement is communicated to the rod 21 through the link .25, the link and rod acting as a toggle lever with relation tothe universal bar. Of course if the universal bar were pivoted with the same axis as the link 25 no movement would be accomplished. In the preferred construction the pivot of the universal bar is at the rear of the connections between the rod 21 and link 25. Other arrangements, however, may he used. By

turning the head 22 any adjustment of these The lever also extends ewriter, the unito permit the escapement of the wheel 19 as I the dogs are reciprocated. (See Fig. 2).

- When the releasing lever 33 is moved forward, it lifts the rod 36 and this rod-running through the slot 39 operates upon the extension 38 wherever the caniagc may be and lifts the bail 40. The movement 'ofthe-luil .is communicated. tiara-Lash the rock levels 41.

mi iaaamm-nantenna-moat lever 45 and from the lever 45 to the sleeve 32. As the sleeve is pulled back through the action of this mechanism the dog 31 is moved out of the path ofthe 'wheel19 so that 5 the carriage may be freely moved in either direction;

What I claim as new is: o 1. In a typewriting machine the combination of a carriage escapement wheel; a reciprocating rod extending in' a direction from front to rear of the machine; the universal bar; a link connecting the universal bar with the rod and arranged to act with the rod as a toggle lever and to communicate the movement of the universal bar to the rod; and dogs actuated by the rod for controlling the movement of the escapement-wheel.

2. In a typewriting machine the combination of a carriage escapement wheel; a recip- 2 rocating rod extending in a direction from front to rear of the machine; a universal bar swingingly mounted with its pivottoward the rear of the machine; a link connecting the rod with the universal bar the pivot between the rod and the link'being in front of the pivot of the universal bar the link connection forming with the bar a toggle lever; and dogs actuated by the rod for controllingthe movement of the escapement wheel.

3. ha typewriting'machine thecombination of a carriage escapement wheel; a reciprocating rod extending in a direction from front to rear of the machine; a universal bar swingingly mounted with its pivot toward the rear of themachine; a link connecting the rod with the universal bar, the pivot between the rod and the link being in front of the pivot of the universal bar and its connection with the universal bar being in front of the connection 40 with the rod said link forming .a toggle lever; and dogs actuated by the rod for controlling the movement of the esca ement wheel.
